Three configuration methods for IPv6 in Linux: 1. automatically obtain the IPV6 address, modify the/etc/sysconfig/network file, add the following configuration text NETWORKING_IPV6 = yes, and then, run the Command service network restart and run the command ifconfig-a to view IPV6 address information: 2013-10-182, static IPV6 address device, modify the/etc/sysconfig/network-script/ifcfg-ethX file and add IPV6INIT = yes (whether to enable IPV6 address upon startup) IPV6_AUTOCONFI = no (whether to use automatic IPV6 Address Configuration) listen 6addr = 2001: da8: 8003: 202: 120: 1: 1 (IPV6 address) Listen 6defaultgw = 2001: da8: 8003: 801: 1 (IPV6 address gateway) run the Command service network restart and run the command ifconfig-a to view IPV6 address information. 3. The IPV6 address of the temporary device and the IPV6 Configuration in Linux: linux supports IPv6. check whether the/proc/net/if_inet6 file exists to check whether your system supports IPv6, if you do not have the following command to load the IPV6 module: # Use ipv6 after modprobe IPV6 is loaded successfully. # ifconfig eth0 inet6 add IPV6ADDR (IPV6ADDR is the IPV6 address of the device to be temporary) # route-A inet6 add default gw IPV6GATEWAY dev ethX (add ipv6 gateway IPV6GATEWAY address for the network device ethX) # ping6 IPV6ADDR (test ping IPV6 address)
